The research reported here has the potential for contributing to a real improvement in the livelihoods of mixed crop-livestock farming households in the dry savannah zone of West Africa through widespread uptake of improved dual-purpose cowpea (IDPC). This technology offers opportunities for the ...

This paper examines the impacts of access to extension services and cooperative membership on technology adoption, asset ownership and poverty using household-level data from rural Nigeria. Using different matching techniques and endogenous switching regression approach, we find that both extensi...
